背面の脊椎 (合計) : 0; 肛門の骨: 0; 脊つい: 98 - 102. Disc-width shorter than its length, width and length about 1,60 to 1,80 times in total length; dorsal fins more or less rounded, its base 1,25 times in its length (Ref. 39215).
Found on coral reefs; as well as mud or sandy bottoms, from shallow water to a depth of 100 m (Ref. 30573, Ref. 114953). Mainly feeds on invertebrates and small reef fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Males reaches maturity at 28 cm TL (Ref. 114953).
Life cycle and mating behavior

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
